CI meaning in Governmental ?

An informant (also called an informer) is a person who provides privileged information about a person or organization to an agency. The term is usually used within the law enforcement world, where they are officially known as confidential human source (CHS), or criminal informants (CI). It can also refer pejoratively to someone who supplies information without the consent of the involved parties. The term is commonly used in politics, industry, entertainment, and academia.

In the United States, a confidential informant or "CI" is "any individual who provides useful and credible information to a Justice Law Enforcement Agency (JLEA) regarding felonious criminal activities and from whom the JLEA expects or intends to obtain additional useful and credible information regarding such activities in the future." The Guidelines do not apply to the use of confidential informants in foreign intelligence or foreign counterintelligence investigations or to informants operating outside the United States in connection with extraterritorial criminal investigations (unless the informant is likely to be called to testify in a domestic case).
